TWISTING- MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 559,565, dated May 5,1896. Application filed July 5, 1893. Serial No. 479,598. (No model.)

To aZZ whom it may concern.-

Be it known that I, LUCIUS BRIGGS, of Glasgo, in the county of NewLondon and State of Connecticut, have invented certain new and usefulImprovements in Twisting- Machines; and I hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawin s, forming part of thisspecification.

This invention has reference to improvements in machines for twistingthread and yarn. u

The object of the invention is to improve the construction of themoistening-trough of a thread-twisting machine.

Another object of the invention is to so construct and support theguide-rods for directing the thread through the inoisteningtrough thatthese guide-rods may be elevated from the trough to lift the thread outof the water, when desirable, or to leave the trough unobstructed whenit becomes necessary to clean the same.

The invention consists in the combination, in a twisting-machine with atrough, of guiderods and supports for the same removably secured in thetrough.

The invention also consists in the combination, with themoistening-trough of a twisting-machine, of guide-rods mounted onsupports which are adapted to liftthe guide-rods and support them atvarious heights above the trough or to remove them entirely from thetrough.

The invention likewise consists in the manner in which theguide-rod-supporting arms are mounted and in the combination therewithof mechanism for operating the same.

Figure 1 represents an end elevation of part of a twisting-machine,showing the trough with the guide-rod-operating device and indicatingtheir relation to the other parts of the mechanism. Fig. 2 represents aplan View of. the trough, the guide-rods, and the mechanism forsupporting and operating the guide-rods. Fig. 3 represents a verticalcrosssectional View of the same, the operation of the guide-rods andsupporting-arms being i11- dicated in broken lines Similar numbers ofreference designate corresponding parts throughout.

yokes being permanently fixed in the trough,

by soldering or riveting. The guide-rods are thus supported slightlyaway from the inner surface of the trough, one extending through thelongitudinal center of the trough and the other near the outer edge ofthe same. The thread is passed under the first rod, over the'second, andthen to the rolls. The waterlevel being above the first rod, the threadpasses through the same and is moistened before reaching the rolls.

In twisting some classes of thread it often becomes desirable to liftthe thread away from the water and to twist a portion of it withoutmoistening. This is impractical without breaking the thread. Again whenthe trough becomes soiled from the sediment carried in the water, aswell as from dust settling therein and the lint scraped from the threadas it passes over the guide-rods, it

becomes necessary to clean the troughs. The water is readily drawn offthrough a perforation in the bottom, ordinarily closed by a stopper; butthe guide-rods and thin yokes being permanently fixed in the troughsgreatly obstruct the cleaning process. Lint and foreign matter willlodge between the bars and the inner surface of the trough, as Well asabout the yokes, from which position it is nearly impossible to dislodgethe same. Much time and labor is required in the operation, whichnecessitates the stopping of at least one side of the twister-frame andgenerally the Whole machine.

In carrying myinvention into practical use I construct a trough 5 of theusual size and shape, but having an inner surface entirely unobstructedfrom end to end. I I support this trough in brackets 6 6, which aremounted in the ordinary way on the table-top 7 of the machine. From thebrackets 6 6 may extend arms 8 and 9, having bearings in which the shaftends of the rolls 10 and 11 are journaled. The rolls may, however, be journaled in arms extending directly from the table-top, or in any othermanner, the supporting of these rolls forming no part of my invention.

Behind the trough 5, and also secured to the table-top 7, are brackets12 12, having bearings formed in their upper portions, and j ournaled inthese bearings is a shaft 13, parallel to the trough. Adjacent to one ofthe brackets 12 a coiled spring 14 encircles the shaft, one end bearingagainst the bracket-face and the other end against the stop collar 15,clamped on the shaft, thus exertingapressure on the shaft in a directionto draw the clampin g-collar of the operating-handle against theadjacent bracket. This spring may, however, be omitted. Either or bothof the shaft end portions are journaled in bearings in the bracket 16,secured to the table-top and hav-. ing ratchet-teeth 17 formed aroundits upper circular part, and on the shaft, adjacent to the bracket 16,is clamped a lever-handle 18, provided with a pawl 19, pivoted to thehandle and engaging the ratchet-teeth 17 when the handle is turnedbackward until the pawl is released.

Extending from the shaft 13, to which they are firmly secured atsuitable distances apart, are the arms 20 20, curving over the pig-tailbar 21, supported near the trough, and having their ends bent to formthe semicircular yokes 22 22, in perforations in which the parallelguide-rods 23 and 2a are secured, these yokes fitting the interior ofthe trough more or less closely.

Fig. 1 represents two threads passing through the ordinary pig-tail,then under the guide-rod 23, over that marked 21, and then over the toproll 10. It is evident that when it is desired to lift the threads outof the water with which the trough is supposed to be partially filled aslight backward movement of the lever-handle will partially rotate theshaft 13, the arms 20, having the yoke 22, will be raised thereby, ifnecessary, to the position indicated in broken lines in Fig. 3, and thethread will be lifted Without breaking the same or interfering with theoperation of the machine. The pawl 19, when the shaft is rotated, willengage the ratchet-teeth 17 of the bracket 16 and will sustain the shaftagainst the weight of the arms 20 and the guide-rods.

When the trough becomes soiled, the throwing back of the handle 18 willraise the yokes 22 and the guide -rods entirely out of the trough,leaving the same unobstructed and in condition to be cleaned in theshortest possible time.

Having thus described my invention, vI claim as new and desire to secureby Letters Patent- The combination, in a twisting-machine, with thetrough 5, of the guide-bars 23 and 24:, the yokes 22 22, formed in partwith the arms 20, for supporting the rods, the shaft 13, mounted inbearings in the brackets 12, to which the arms 20 are secured, thebracket 16 having the ratchet-teeth 17, the handle 18 fastened on theshaft, and the pawl 19 pivoted to the handle and adapted to engage theratchet-teeth 17, as and for the purpose described.
